目的:采用有限元分析方法研究单髁置换术后膝关节表面应力变化,为深入了解单髁置换术优势及劣势提供依据。方法:对6例单髁置换术后及6例正常人膝关节屈伸活动时关节表面应力变化进行动态有限元分析,并与项目组前期全膝关节置换术后关节表面应力分析进行对比。结果:正常组屈曲30°以后内侧间室应力大于外侧间室(P<0.05);单髁置换组屈曲0°、60°、90°时内侧间室应力大于外侧间室(P<0.05);全膝置换组在所有屈曲角度下内侧间室应力大于外侧间室(P<0.05)。屈曲60°及90°时单髁置换组内侧间室应力大于全膝置换组(P<0.05);所有屈曲角度下,单髁置换组外侧间室应力大于全膝置换组外侧间室应力(P<0.05);屈曲0°、30°、60°及120°时,单髁置换组外侧间室应力都大于正常膝组(P<0.05)。结论:单髁置换术可增加膝关节关节面应力及加速对侧间室关节炎发展,从而影响手术远期疗效,但在严格把握手术适应症、优化手术操作、假体适当改良、指导患者合理康复后,该术式仍具有优势。  相似文献

Purpose

C-reactive protein (CRP) is an acute-phase biomarker responding to surgical trauma. Typically, a first peak is observed at day 2 with a reduction at day 4 and normalization 3–6 weeks after surgery. CRP is often linked to prosthetic joint infection when elevated values are present longer time after surgery. The aim of this study was to analyse the kinetics of CRP in different types of minimally invasive (MI) arthroplasty and to observe if there were significant differences in between MI total knee arthroplasty (TKA), patient-specific instruments (PSI) TKA and unicompartmental arthroplasty (UKA).

Materials and methods

Three hundred and seventy-two patients were prospectively studied with a blood test measuring CRP at day 2, 4, 21 and 42 in 3 different groups of patients: 257 MI TKA, 55 PSI TKA and 60 UKA. Mean peak values and kinetics were compared in between different groups of MI arthroplasty.

Results

There was a significant age difference in the three MI arthroplasty groups. The difference in mean age for the conventional MI TKA group of 68.8 ± 9.8 years, 58.5 ± 11.7 years for the unicompartmental group (P < 0.05) and 63.3 ± 9.6 years for the PSI group (P < 0.05) was significant. Mean CRP level, for the entire study group, on day 2 was 16.7 ± 8.8 mg/dl that gradually decreased to 13.6 ± 7.8 mg/dl on day 4. On day 21 and 42, median CRP level was 0.6 (0–20) and 0.4 (0–7) mg/dl, respectively. Peak CRP values were lower for UKA compared to TKA at day 2 (11.6 vs. 17.5 mg/dl) and day 4 (8.0 vs. 15 mg/dl), but this was not observed for PSI–assisted arthroplasty (18.9 vs. 17.5 mg/dl). There was a trend for faster CRP normalization in UKA compared to the two other groups at day 21 and at day 42 and for PSI TKA to have a lower mean level at 4 days (12.9 vs. 15 mg/dl). There was no statistical difference in the normalization rate of PSI–assisted versus MI TKA.

Conclusion

Kinetics of CRP in MI arthroplasty are identical to the published kinetics of conventional TKA. Most patients normalize CRP at 3 weeks; however, 18 % does not by 6 weeks. This is not a sign of early prosthetic joint infection. Peak values are significantly lower for UKA but not for PSI TKA.

A man, aged 55, presented with a spontaneous haemarthrosis of his right knee, 1 year after an unicompartmental knee replacement. This case showed an atraumatic rupture of the metal marker wire of an all-polyethylene inlay tibial implant which caused a destruction of the polyethylene surface and a disseminated synovitis of the right knee. This is a rare but destructing complication following an unicompartmental knee arthroplasty.  相似文献

BackgroundFollowing rehabilitation for total knee arthroplasty, “quadriceps avoidance gait”, defined by limited knee flexion angle excursion during walking, persists and contributes to poor long-term outcomes. Given the presence of several post-surgical impairments, identifying the contribution of multiple factors to knee flexion angle excursion is important to developing targeted interventions to improve recovery after total knee arthroplasty.Research questionsWhich outcomes continue to improve following rehabilitation for total knee arthroplasty? What are the primary contributors to impaired knee flexion angle excursion during walking following total knee arthroplasty?MethodsPeak muscle strength and rate of torque development of the quadriceps, hip abductors, and hip external rotators, five-time sit-to-stand test, Knee Injury & Osteoarthritis Outcome Score, and gait mechanics were assessed in 24 participants at three and six months post-surgery. Paired sample t-tests or Wilcoxon Signed-Rank tests were used to compare outcomes between assessments. Stepwise multiple linear regression were used to assess the contribution of each measure to knee flexion angle excursion.ResultsSignificant improvements were noted in all outcomes except hip external rotation rate of torque development, gait speed, and knee flexion angle excursion. Quadriceps rate of torque development and knee pain significantly contributed to knee flexion angle excursion at three months (Adjusted R2 = 0.342), while quadriceps rate of torque development and peak hip external rotation strength significantly contributed at six months (Adjusted R2 = 0.436).SignificanceWhile higher pain levels at three months and greater peak hip external rotation muscle strength at six months contribute to impaired knee flexion angle excursion, quadriceps rate of torque development was the primary contributor to knee flexion angle excursion at both three and six months after surgery. Implementing strategies to maximize quadriceps rate of torque development during rehabilitation may help to reduce quadriceps avoidance gait after total knee arthroplasty.  相似文献

Physical activity after total joint replacement: a cross-sectional survey.   总被引:1,自引:0,他引:1  
OBJECTIVE: To determine the level of physical activity participants are able to perform at a minimum of 1 year after primary total hip or knee replacement. DESIGN: Cross-sectional survey. SETTING: A tertiary care arthroplasty center. PARTICIPANTS: A total of 170 primary total hip and 184 primary total knee arthroplasty patients. INTERVENTIONS: The University of California Los Angeles (UCLA) activity score was mailed to 242 primary hip and 225 primary knee arthroplasty patients. Patients were abstracted from a prospectively tabulated arthroplasty database and pre-selected for good/excellent clinical outcomes as determined by 1 year postoperative Knee Society (KSS) and Harris Hip (HHS) scores. Clinical outcomes including the Oxford Hip/Knee score were collected preoperatively, and at 6 and 12 months postoperatively. Correlations between UCLA scores, demographics, and clinical outcomes were calculated using Pearson's correlation. MAIN OUTCOME MEASUREMENTS: Harris Hip Score, Oxford Hip Score, Knee Society Score, Oxford Knee Score, and UCLA Activity Scale. RESULTS:: Postal survey response rates for hips were 70.2% (170 of 242) and 81.8% for knees (184 of 225). Mean results at postoperative year 1 include: HHS (94.8), Oxford Hip Score (16.6), KSS clinical score (95.9), KSS function score (95.0), and Oxford Knee score (18.2). For both primary total hip arthroplasty and total knee arthroplasty patients, median UCLA score was 6, indicating moderate activity levels at a mean follow-up of 40.7 months for hips and 36.6 months for knees. CONCLUSIONS: UCLA scores indicate the average total joint replacement patient maintains a moderate activity level, and many perform active/very active levels of activity.  相似文献

We present the case of a patient who after uncemented unicompartmental knee arthroplasty developed a large osteolytic cystlike area in the lateral aspect of the tibial metaphysis, contralateral to a well-fixed tibial component at revision surgery. The lesion contained fibrotic soft tissue, evidence of a foreign-body giant cell reaction and polyethylene particles, but no metal wear debris, infection, or malignancy. This case demonstrates that there is a direct communication between the joint cavity and the cyst.  相似文献

BackgroundThe aim of the present study is to compare sagittal gait kinematics of ankle, knee and hip joints between subjects with unicondylar and total knee arthroplasty and age matched healthy controls. Since unicondylar knee replacement is a less invasive procedure, which more closely preserves knee joint anatomy, we hypothesized that one year post unicondylar knee arthroplasty patients would demonstrate more normal gait patterns than patients with total knee arthroplasty.Research questionDo unicondylar and total knee arthroplasty patients display similar gait kinematics one year after surgery?MethodsFourteen subjects (8 posterior stabilized and 6 medial unicondylar knee replacements) that were one year post surgery, and 6 healthy control subjects underwent a 3D gait analysis and a physical examination (range of motion, muscle strength). Statistical parametric mapping was used to compare gait kinematics of the lower limbs between groups. Additionally, differences in peak angles and clinical outcomes were assessed using a one-way ANOVA between subjects analysis.ResultsBoth knee replacement groups showed reduced knee flexion range of motion and reduced muscle strength at the operated leg compared to the control group. Subjects with TKA demonstrated reduced knee flexion at loading response and midstance of the gait cycle. Both UKA and TKA demonstrated significantly less knee flexion during swing.SignificanceThe results of this study demonstrate arthroplasty-specific differences in muscle strength, range of motion and gait kinematics of the lower limb one year after knee surgery. Future planning of post-surgery follow-up should addresses these arthroplasty-specific weaknesses and gait deviations.  相似文献

Purpose

The purpose of this study was to describe patient-related functional outcomes after fast-track total knee arthroplasty and unicompartmental knee arthroplasty. Furthermore, we wanted to assess physical areas where an additional need for rehabilitation could be identified, and finally, we wanted to describe the association between physical function, health-related quality-of-life (HRQOL) and patient satisfaction.

Methods

The study consisted of 211 consecutive fast-track patients of which none received additional rehabilitation beyond an instructional exercise plan at discharge, which was adjusted at one outpatient visit. The patients filled in 3 questionnaires (EQ-5D, SF36 and a disease-specific questionnaire) at 2 time points before the operation and 2 time points after the operation. The observed results were compared to normative population data for EQ-5D and SF36.

Results

Four months after the operation, the patients had reached a HRQOL level of 0.82 (SD 0.15), which was lower than the background population norm of 0.85 (n.s.), whereas it equaled the population norm at 12 months (n.s.). For SF36, physical function was 62.8 (SD 23.0) at 4 months and 66.2 (SD 24.1) at 12 months, which was lower than the background population norm of 75.0 (P < 0.01). No or mild pain and good function ability were associated with high HRQOL and patient satisfaction at follow-up.

Conclusions

There seems to be an additional need for postoperative rehabilitation after fast-track total knee arthroplasty and unicompartmental knee arthroplasty regarding early functional outcome. No or mild pain and good functional abilities at 4 months are associated with high HRQOL and patient satisfaction at 4- and 12-month follow-up.
